Retainer for a firework that can be used indoors

ABSTRACT

A retainer for a firework that can be used indoors which can also be placed on the neck of a bottle.

The invention relates to a retainer for a firework that can be used indoors.

There are a multiplicity of proposals for retainers, to which firework rockets which are used outdoors can be fixed in such a way that they can be held reliably in the desired direction and can be let off comfortably. Said retainers are not conceived and also cannot be used for indoor fireworks.

U.S. Pat. No. 3,580,173 A describes a joke article which can have the shape of a bottle and can contain a firework.

DE 41 09 219 A describes a cork for a sparkling wine bottle, which cork contains a firing charge and confetti. When the cork is detached, the firing charge is ignited automatically, with the result that a part of the cork blows off dramatically and confetti is sprayed.

DE 93 20 162 U1 and DE 92 10 670 U1 describe table fireworks which consist of a circularly cylindrical vessel, on the bottom of which pyrotechnic material is arranged, above which an object is arranged which is lifted up out of the vessel upon ignition of the pyrotechnic material.

CN 200999119 Y discloses a similar principle, the vessel being disguised as a bottle.

The object on which the invention is based consists of it being possible for a small indoor firework to be fastened in an attractive way without complicated handling, in such a way that said indoor firework can be let off without risk.

In order to achieve the object, it is provided that the retainer, to which a firework is fastened or can be fastened, is configured such that it can be plugged onto a bottle.

A firework is fastened or can be fastened to the upper side of the retainer. For example, said firework can have the shape of a rod which is plugged with its lower end in a depression of the retainer and which is ignited at its upper end.

In one preferred embodiment, one or more parts of the retainer encloses/enclose the bottle neck and/or the closure which is arranged on the bottle in a manner which closes the bottle opening. Here, the one or more parts of the retainer bears/bear with elastic prestress against the bottle neck or the closure of the bottle.

An advantage of this design is that it can be used for any desired, closed or open bottles. For example, the retainer can be attached to a bottle of sparkling wine, with which a birthday celebration is to be initiated, and the firework can be let off before the conventional opening of the bottle.

For example, that part of the retainer which encloses the bottle neck and/or closure can be configured as a vertical circularly cylindrical circumferential face and/or conical or frustoconical circumferential face which is open at the bottom and from which ribs project radially to the inside, which ribs can be bent slightly under elastic deformation in the circumferential direction. As a result, one design of a retainer can fit a wide range of diameters of bottle necks and/or bottle closures.

Other possible designs for that part of the retainer which is secured on the bottle are, for example, a hollow truncated cone which narrows conically from the bottom to the top, or clamping limbs which can be pivoted about horizontal axes, are prestressed elastically or are pressed on by springs.

In another preferred embodiment, the retainer itself is the closure of a bottle. Like conventional bottle closures, it can either bear here under elastic prestress against the inner circumferential face or can enclose the outer circumferential face of the bottle neck and can close the opening with a lid.

This design is suitable, for example, when a drinks supplier wishes to provide drinks specifically for particularly festive occasions. In addition to the less common use as a retainer for a firework, the design can also be used as a re-usable bottle closure.

The retainer can appear in every embodiment. To this end, two possible examples are to be mentioned:

In one preferred embodiment, the retainer has the shape of a crown in a side view, with the result that spikes are therefore arranged behind one another in the circumferential direction, upward from the retainer and possibly also radially to the outside. The shape of the crown is well suited to many festive occasions.

In a further preferred embodiment, the retainer has the shape of a flower in a side view, with the result that leaf-like projections which are arranged behind one another in the circumferential direction protrude upward from the retainer and possibly also radially to the outside, it also being possible for the individual projections to overlap in the circumferential direction. The shape of the flower is well suited to many festive occasions.

The invention will be illustrated using drawings relating to two exemplary embodiments.

FIG. 1 shows an exemplary retainer 1 according to the invention in a side view, which retainer 1 is configured as a crown, the retainer 1 being fitted with a firework 2 and being plugged onto the neck of a bottle 3.

FIG. 2 shows the retainer from FIG. 1 on its own from below.

FIG. 3 shows a further retainer 10 according to the invention on its own in a lateral sectional view.

FIG. 4 shows the retainer from FIG. 3 from above.

Both retainers 1, 10 which are shown have a sleeve 1.2, 10.2 which is dimensioned for enclosing the upper part of the neck of a bottle 3. Flexible ribs 1.3, 10.3 protrude to the inside away from the inner circumferential face of the sleeve 1.2, 10.2. Said ribs are bent by being plugged onto a bottle neck, with the result that they bear with pressure against the bottle neck, whereby the retainer 1, 10 is fixed releasably on the neck of the bottle 3.

In the example according to FIG. 1 and FIG. 2, the flexible ribs 1.3 do not only simply protrude radially away from the inner circumferential face of the sleeve 1.2, but rather their orientation also has a component in the circumferential direction. In comparison with an embodiment of a retainer with purely radially oriented ribs, the plugging onto a bottle is therefore facilitated.

The firework 2 can already be connected to the retainer 1, 10 ex factory or can be connected to it by the user. Adhesive connections, plug-in connections (spline connections) and snap-action connections are well suited as connecting methods.

The retainer 10 according to FIG. 3 and FIG. 4 has a cylindrically circumferential sleeve 10.2 which is closed off on one side by a covering face which is perforated by apertures 10.6, on the outer side of which hook parts 10.5 are attached for connecting the retainer 10 to a firework. In an axial projection direction of the apertures 10.6, ribs 10.3 which protrude radially from the inner circumferential face of the sleeve 10.2 are attached in the interior of the sleeve 10.2. In comparison with an embodiment without apertures 10.6, the embodiment shown, in the case of readily deformable ribs 10.3, can be produced substantially more simply by plastic injection molding.

Retainers according to the invention can typically be produced by plastic injection molding. Retainers according to the invention can therefore be produced so inexpensively that a single use of the retainers may also be economically appropriate.

 4. The retainer as claimed in claim 3, wherein, in the mounted state, in comparison with the unmounted state, the ribs are bent circumferential direction around the neck of the bottle.
 5. The retainer as claimed in claim 1, wherein a part of the retainer is a bottle closure.
